IPv6 not available on some arm_linux and alpine-linux machines

[smlambert]

Please set the title to indicate the test name and machine name where known.
As seen in adoptium/aqa-tests#4257 (comment),

Execution failed: `main' threw exception: java.lang.UnsupportedOperationException: IPv6 not available

To make it easy for the infrastructure team to repeat and diagnose, please
answer the following questions:

• test suite/name (e.g, BUILD_LIST, TARGET, CUSTOM_TARGET)?
• a link into recent Test_ job on https://ci.adoptopenjdk.net which showed the failure
  • https://ci.adoptopenjdk.net/job/Test_openjdk19_hs_extended.openjdk_arm_linux_testList_2/33/(rerun in Grinder/6424)
  • https://ci.adoptopenjdk.net/job/Test_openjdk19_hs_extended.openjdk_x86-64_alpine-linux_testList_2/34/
• Hyperlink to re-run in Grinder: rerun link
• Is there an existing issue elsewhere covering this?
• Which machine(s) does it work on? test-docker-ubuntu2204-armv8-2
• Which machine(s) does it fail on? test-docker-ubuntu2004-armv7l-1, test-docker-alpine314-x64-1

Any other details:

On dockerhost-equinix-ubuntu2004-armv8-1, the host of test-docker-ubuntu2004-armv7l-1, I added { "ipv6": true, "fixed-cidr-v6": "fd00::/80" } to /etc/docker/daemon.json and restarted docker.

The failing tests (jdk_net_2) pass https://ci.adoptium.net/view/Test_grinder/job/Grinder/6755/console

Going to do the same for test-docker-alpine314-x64-1

[Haroon-Khel]

jdk_net passes on test-docker-alpine314-x64-1 https://ci.adoptium.net/view/Test_grinder/job/Grinder/6758/console. Will check other nodes before closing

Let's not close this just yet and lose this setup info. A couple of questions:

• Is there anything preventing this from be added into the dockerhost playbook? If not, let's make sure we do that
• Was it affecting all containers on each host or just a subset, and if a subset do we know what was special about the ones it worked on? (Were different distributions all behaving the same for example?)
• Is the fix required on all dockerhosts?

[Haroon-Khel]

It is already in the playbooks

infrastructure/ansible/playbooks/AdoptOpenJDK_Unix_Playbook/roles/DockerStatic/tasks/main.yml

Line 6 in 052bdf4

- name: Enable ipv6 on Dockerhost

But I do not know why the fix wasnt present on the dockerhost

[Haroon-Khel]

Some jdk_net tests still fail on the following machines despite the above fix

The jdk_net tests passed on test-docker-ubuntu2204-x64-1 https://ci.adoptium.net/view/Test_grinder/job/Grinder/6836/, which is hosted on dockerhost-equinix-ubuntu2004-x64-1, while test-docker-ubuntu2204-x64-2 is hosted on dockerhost-equinix-ubuntu2204-x64-1. I'll create another ubuntu 2204 container on the passing dockerhost machine

[Haroon-Khel]

Closing this issue since the ipv6 tests pass. There are some problematic containers on dockerhost-equinix-ubuntu2004-x64-1, for which I have opened #3010
